2008 SATURN ASTRA Fluid

Brakes
Brake Fluid
The brake master cylinder and, on
manual transmission vehicles,
the clutch hydraulic system use the
same reservoir. The reservoir is
lled with DOT-4 brake uid.
SeeEngine Compartment Overview
on page 9-6for the location of
the reservoir.
There are only two reasons why the
brake uid level in the reservoir
might go down. The rst is that the
brake uid goes down to an
acceptable level during normal
brake lining wear. When new linings
are put in, the uid level goes
back up. The other reason is that
uid is leaking out of the brake
or clutch hydraulic system. If it is,have the brake or clutch hydraulic
system xed, since a leak means
that sooner or later the brakes
or clutch will not work well.
It is not a good idea to top off the
brake uid. Adding brake uid
will not correct a leak. If uid is
added when the linings are worn,
there will be too much uid
when new brake linings are
installed. Add or remove brake uid,
as necessary, only when work is
done on the brake or clutch
hydraulic system.
{CAUTION
If your vehicle has too much
brake uid, it can spill on the
engine. The uid will burn if the
engine is hot enough. You or
others could be burned, and
your vehicle could be damaged.
Add brake uid only when work
is done on the brake and/or
clutch hydraulic system.Refer to “Scheduled Maintenance”
in the Limited Warranty,
Maintenance and Owner Assistance
Information manual to determine
when to check the brake uid.
Checking Brake Fluid
The brake uid can be checked
without taking off the cap by looking
at the brake uid reservoir.
The uid level should be above
MIN. If it is not, have your brake
hydraulic system checked to see
if there is a leak. After work is done
on the brake hydraulic system,
make sure the level is above the
MIN but not over the MAX mark.
What to Add
When you do need brake uid,
use only DOT-4 brake uid.
It is recommended that you ush
the brake hydraulic system and
rell it with new DOT-4 uid
at a regular maintenance service
every two years. See “Additional
9-22 Vehicle Service and Care
ProCarManuals.com

Required Services” in the Limited
Warranty, Maintenance and
Owner Assistance Information
manual. Use new brake uid
from a sealed container only.
See “Recommended Fluids and
Lubricants” in the Limited Warranty,
Maintenance and Owner Assistance
Information manual.
Always clean the brake uid
reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{CAUTION
With the wrong kind of uid in
the brake hydraulic system,
the brakes might not work well.
This could cause a crash.
Always use the proper brake
uid.Notice:
Using the wrong uid can
badly damage brake
hydraulic system parts.
For example, just a few drops
of mineral-based oil, such
as engine oil, in the brake
hydraulic system can
damage brake hydraulic
system parts so badly that
they will have to be replaced.
Do not let someone put in
the wrong kind of uid.
If you spill brake uid on your
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on your vehicle. If you
do, wash it off immediately.
SeeExterior Cleaning on
page 9-75.
Brake Wear
Your vehicle has disc brakes.
Notice:Continuing to drive
with worn-out brake pads could
result in costly brake repair.
Front disc brake pads have built-in
brake pad wear indicators that
make a high-pitched warning sound
when the brake pads are worn
and new pads are needed.
The sound can come and go or be
heard all the time your vehicle is
moving, except when you are
pushing on the brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead
to an accident. When you hear
the brake wear warning sound,
have your vehicle serviced.
Vehicle Service and Care 9-23
ProCarManuals.com

page 9-80. Follow all manufacturers’
directions regarding correct
product usage, necessary safety
precautions and appropriate
disposal of any vehicle care product.
Rinse the vehicle well, before
washing and after to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the nish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and
water spotting.
High pressure car washes may
cause water to enter the vehicle.
Avoid using high pressure washes
closer than 12 inches (30 cm)
to the surface of the vehicle.
Use of power washers exceeding
1,200 psi (8 274 kPa) can result
in damage or removal of paint
and decals.Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better,
and not stick or squeak. Apply
silicone grease with a clean cloth.
During very cold, damp weather
frequent application may be required.
See “Fluids and Lubricants” in the
Index of the “Maintenance and
Warranty and Owner assistance
Information” manual.
Wheels and Trim — Aluminum
or Chrome
Your vehicle may have either
aluminum or chrome-plated wheels.
Keep the wheels clean using a soft
clean cloth with mild soap and water.
Rinse with clean water. After rinsing
thoroughly, dry with a soft clean
towel. A wax may then be applied.
Notice:Chrome wheels and
other chrome trim may be
damaged if you do not wash your
vehicle after driving on roads
that have been sprayed withmagnesium, calcium or sodium
chloride. These chlorides are
used on roads for conditions
such as ice and dust. Always
wash your vehicle’s chrome with
soap and water after exposure.
Notice:If you use strong soaps,
chemicals, abrasive polishes,
cleaners, brushes, or cleaners
that contain acid on aluminum or
chrome-plated wheels, you
could damage the surface of the
wheel(s). The repairs would
not be covered by your warranty.
Use only approved cleaners on
aluminum or chrome-plated
wheels.
The surface of these wheels is
similar to the painted surface of your
vehicle. Do not use strong soaps,
chemicals, abrasive polishes,
abrasive cleaners, cleaners with
acid, or abrasive cleaning brushes
on them because you could damage
the surface. Do not use chrome
polish on aluminum wheels.
